This bubble chart visualizes the correlation between average torque, horsepower, and highway MPG across 31 car makes. Each circle represents a make, positioned by its horsepower and torque values, with bubble size encoding highway MPG and color distinguishing brands. The visualization includes interactive tooltips on hover and a dual legend for both bubble radius and color categories. Built with D3 v7, it utilizes SVG rendering, scaleLinear for axes and sizing, scaleOrdinal for color assignment, and event handlers for tooltip interactions.
